21x11.5 hood for a 1000 watt 4 plant grow

thats what i have now but i would like to have a better(wider footprint )reflector...got 4 waterfarms under a 1000 watt hps in about a 4x4 and ceilings 8 ft...

I replaced my reflector a couple of months ago, with the biggest reflector in the shop....biggest mistake ever, had heat issue from day one, cut myself a few times too, in the end I went back to the tiny reflector I prefer, at least I can work around it ...just saying ...lol

You cant beat a Blockbuster for a 4x4 footprint. If your existing hood isnt bright on the corners try moving it up a few inches until you get a new hood.
